'l i; all whom it may conce/m p Be it known that '1., Jenn W. HEAPHY, oRochester, in vthe ,county iof Monroe and State of New York, have d tedcertain ner.' and useful lmprorenients in Tumblingarrcls; and l dohereby declare the following to be a full, clear, and enact descriptionbeing had to the ue forming e pei-rt of to the re ferenceumerels markedthereon.

Mv invention has for its object to proyide novel form oftumbling-barrel, such as my be employed for the purpose of polishu .ngor cleaning or otherwise treating small articles yby an' agitatingprocess, one of the purposes ot the invention being to provide :iconstruction that permits the more ready feeding' or discharging of thearticles to or .from the machine.

A further object of the improvements is to afford an arrangement thatwill eil'ect a, quicker and more thorough agitation of the articles, thestructure by which this result is accomplished being simple andecouomicul to manufacture.

To these and other ends the invention consists in certain improvementsland,combiioaY 'tions of parts, all as will be hereine'fter more fullydescribed, the novel tentures being pointed out in the claims et the endof the specification.

The inrention. is susceptible of various applications, a more common usebeing in the polishing or abrading of smell articles of metal or othermaterial and in thc pres ent embodiment, which shows an instance of amember carrying out the invention, the tumbler comprises a body A whichis substantially cylindrical and is provided with the ends or heads Bwhich extend beyond the periphery of 4the body and are connected bybrace rods C. To the heads E are secured journals mounted in bearings,one of said jouwe-ls being provided with a, tilted ES FATE Patented Mar.2i. 1.916.

The body of the tumbler is preferablyv formed of Celluloid althoughitmay bc constructed of any other desirable material from a sheet thatis bent u ,on itself circulerly to the desired size o cylinder. Theopposite ends of the sheet from which the tumbler is formed are attachedtogether along the lines G and H, one end being extended to define atapering portion which overlaps the under ,layer of the body as shown inFigs. 1 and 2. The overlapping portions are offset or embossed inwardlyand outwardly as designated at I and J thereby affording :i taperingopening K into which the articles can readily be fed and fioni\wliichtheir discharge is easily eli'eeted. The articles are led to thetumble'rwhile il is in the position shown in Fig. 2, and are thereafter gitatedand treated, by rotation of the cylinder in a clock-wise .direction Todischarge the articles from the cylinder, its direction of movement isreversed so that as the opening K moves in an anti-clockwise direction,the contents are quickly removed, such removal being assisted by thetapering character of the discharging opening.

lt is quite desirable that the article undergoing treatment bo agitatedto a maximum degree und to this end l, may employ means for causing anadditional movement of the. articles toward and troni the ends of thecylinder and fordropping them from the top to the bottom of the cylinderat intervals. This may be accomplished by providing the body of thetumbler with a pluality or inwardly projecting bullies or ribs L whichare preferably formed by embossing, and extend in curved lines frompoints between the center and ends of the cylinder to near the center ofthe cylinder, as shown in Fig. 'l. The result of this construction isthat as the tumbler rotates, the curved ii-ailles engage the articlesand eflect movenient of the latter successively toward the center lineof the cylinder. Certain of the balles li terminate. at a point adjacentto a pocket )rejecting offset body of the cylinder. moved inwardly,array from the ends of the, cylinder oy the bullies L, arc caught up bythe. mollet M- and carried upwardly by the latter until it is nearly atthe limit of its upward movement, whereupon they are dropped to thebottom and the operation is repeated.

' The construction described affords a novel and extremely etlicientarrangement for the purposes set forth, the tumbler being of simple andcomparatively economical construction While at the saine time, quitestrong, and rigid enough for the purposes intended, and it is to beunderstood that the present application is intended to cover anydepartures from the specific construction described that may come withinthe terms of the appended claims.

I claim as my invention:

1. A tumbling barrel comprising a substantially cylindrical body formedfrom an integral sheet of material which embodies a tapering overlappingportion, the part of the body underlying said overlapping portion beingoffset from the periphery so as to form a tapering charging anddischarging opening. y

2. A tumbling barrel comprising a substantially cylindrical body and atapering overlapping portion which is offset from the periphery of thebody so as to form a taperlng charging and -discharging opening.

3. A tumbling barrel comprising a sub stantially cylindrical body havinga plurality of inwardly projecting baflles which entend in curved linestoward the center of Y the center and the ends the body from pointsbetween the center and the ends of the body, the inner ends of thebafles terminating adjacent to a recess or pocket formed by an outwardlyextending offset portion on the body.

4. A tumbling barrel comprising a substantially cylindrical body andoverlapping portions which are offset in opposite directions from theperiphery of the body affording a charging and discharging opening, thebody being provided with a recess or pocket approximately opposite saidcharging and discharging opening formed by an outwardly extending offsetportion in the body, and a plurality of inwardly projecting battleswhich extend in curved lilies toward the center of the body from pointsbetween off-the body, the inner ends of the battles terminating adjacentto said recess or pocket.

5. A tumbling barrel comprising a substantially cylindrical bodyembodying a tapering portion offset from the periphery of the body andoverlapping a portion of the body which is offset in the oppositedirection from the periphery of the body so as to form a taperingcharging and discharging opening.
